Mesoscale Eddies Reorganize Subsurface Oxygen Minimum Layer in the Subtropical North Atlantic

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Mesoscale eddies play a key role in regulating oceanic physical and biogeochemical environments. However, their influence on vertical oxygen distribution remains poorly constrained by observations. Using 32 years (1993–2024) of in situ oxygen observations from the Bermuda Atlantic Time‐series Study site combined with satellite‐tracked eddies ...

Observed Multi‐Decadal Acceleration of Globally Averaged Abyssal Ocean Warming

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Given sparse historical data in the deep and abyssal ocean, previously only multi‐decadal temperature trends have been estimated from observations there on a global scale. Full‐depth CTD sampling started circa 1970, with the first decadal global ship‐based survey occupied in the 1990s, and the first regional pilot array of Deep Argo floats ...

Low Cross‐Product Agreement in Global Coastal Marine Heatwaves (1982–2023) and Implications for Trend Attribution

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Coastal marine heatwaves (MHWs) derived from satellite and blended sea surface temperature (SST) products often disagree, but the magnitude and drivers of this uncertainty remain poorly quantified. Using four daily SST products from 1982 to 2023, we quantify agreement at 9,946 global coastal points using two inter‐product intersection‐over ...

Marine Heatwave Imprints on Salinity in the Northwest Atlantic

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Marine heatwaves (MHWs) are increasing in frequency and intensity in global boundary current systems such as the Gulf Stream (GS), where ocean circulation regulates upper‐ocean heat and water‐mass properties. We examine temperature–salinity co‐evolution during MHWs in the Northwest (NW) Atlantic using satellite observations and ocean ...

Reduced Wind Power on Oceanic Near‐Inertial Internal Waves in a Warming Climate

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Wind power on oceanic near‐inertial internal waves (WI ${W}_{\mathrm{I}}$) is one of the major energy sources to sustain ocean turbulent diapycnal mixing. However, its response to global warming remains poorly understood. Using a high‐resolution climate simulation that simulates WI ${W}_{\mathrm{I}}$ reasonably well, we show that under a high ...

Evaporation and Cold Pools Beneath Trade Cumulus Clouds

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 13, 16 July 2026.
Abstract The sources of air and water vapor in the tropical trade‐wind Atlantic subcloud boundary layer (SBL) are analyzed using in situ measurements of temperature, specific humidity, and stable water isotopologues (HDO and H218O) from shipboard observations in January‐February 2020.

Opposite Trends of Eddy Kinetic Energy in the Tropical Indo‐Pacific Ocean Since the 1990s

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Oceanic mesoscale eddies are pivotal in redistributing mass and heat. Despite a warming‐induced increase in global oceanic stratification, previous studies have reported a global increase in mesoscale eddy activity, particularly in eddy‐rich regions, pointing to a complex and regionally contingent response to climate change.

Weak 21st‐Century AMOC Response to Greenland Meltwater in a Strongly Eddying Ocean Model

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Climate models project that the Atlantic Meridional Overturning Circulation (AMOC) will weaken in the 21st century, but the magnitude is highly uncertain. Some of this uncertainty is structural, as most climate models neglect increasing meltwater from the Greenland ice sheet and do not explicitly capture mesoscale ocean eddies.

Calibration of a Neural Network Ocean Closure for Improved Mean State and Variability

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Global ocean models exhibit biases in the mean state and variability, particularly at coarse resolution, where mesoscale eddies are unresolved. To address these biases, parameterization coefficients are typically tuned ad hoc. Here, we formulate parameter tuning as a calibration problem using Ensemble Kalman Inversion (EKI).
